<div align="left"><font face="Arial"><span style="font-size:10pt">>Reply-To: </span></font><font face="Arial" color="#008000"><span style="font-size:10pt"><u>asterisk-users@lists.digium.com</u></span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">></span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>I have been investigating more tight integration between * and the Nortel MICS...  </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>it appears that it is at least theoretically possible to have * store voicemail </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>and log which stations call where. </span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">The problem here is that you need to have MCDN to get the message </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">notification from the network to the MICS. MCDN only works if you're using the </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">SL1 protocol on the span, and * doesn't support SL1 (no one but Nortel does because</span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">it's their proprietary protocol).</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>Both require a T1 card.  The T1 card requires either a clocking module or </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>the 6-port fiber module to provide T1 timing.  Naturally a T100P or TE405P </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>is required on the * side.</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">For the MICS you'll either need a services cartridge, or a COMBO cartridge </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">(there's two types of 6-port cartidges - only the COMBO version has the services </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">cartridge built-in). Other folks have connected * to MICS via a PRI span, so it definitely </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">do-able</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>To log which stations call where you set up the OLI# on the MICS to set </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>the outgoing caller ID to the station # + some prefix.  i.e. you're really </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>configuring the MICS to set the outgoing CID to be a number in a DID pool.</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">Sure. Plus you can do some awesome routing tricks using the Routing service</span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">in the MICS.</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>However to get * to gracefully handle the MICS voicemail it appears that </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>you can utilize the centralized voicemail feature on the MICS.  It is used </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>to allow Norstar systems to share a voicemail system.  This is perfect.  :-) </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>However it seems that in setting it up the T1 needs to be set up to use </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>the SL1 protocol.</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">Yep. More specifically, you need MCDN (Meridian Customer Defined Network)</span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">to take advantage of centralized mail.</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>Does anyone have any more information on the SL1 protocol?  I don't expect </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>* to support it currently but I'm more interested in investigating what is </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>required.  I think that allowing * to play with these systems nicely will </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>go a LONG way in furthering Asterisk's penetration into the small/mid </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>business  market. </span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">You almost have to know how to hack/spoof the D-channel messaging. SL-1 </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">and MCDN are Nortel proprietary, and I don't believe there's any easy way to</span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">access the specs on those.</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">Why not use a VMI on the MICS, and tie em together with FXO cards in the *?</span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>Aside: Since we moved to the new building (and * is </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>handling all calls and faxes for us) our * system has handled over 11500 </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>calls.  That's over 5500 calls a month, incoming, outgoing and faxes.  </span></font></div>
<div align="left"><font face="Arial"><span style="font-size:10pt">>Not a bad start.  :-) </span></font></div>
